Answer:
Step-by-step explanation:
F(x) is another name for y
If you make a table of values, you can plot the coordinates of this quadratic equation.
When "x" is 0, y is 3
U can’t do that
U can’t do constant-variable or vice versa
<span>Triangle RST was dilated by a scale factor of 1/2
Given: </span><span>triangle R'S'T', is an isosceles triangle, with each leg measuring 8 units.
Pre-image:
measure of pre-image * scale factor = measure of resulting image
measure of pre-image = measure of resulting image / scale factor
measure of pre-image = 8 / 1/2
measure of pre-image = 8 * 2/1
measure of pre-image = 16 units.</span>
Because the shapes are similar find 1 side of the small shape and 1 side of the big shape that are in the same place/that are similar to each other.
The bottom part of both shapes have a number so let’s use those.
The numbers (in ratio form) are 8:24
The GCF (greatest common factor) that goes into both numbers is 8.
So divide each side by 8 (8 divided by 8 and 24 divided by 8)
Now you have 1:3. (Again, in ratio form)
This is your scale factor.
So in the top box put 1 and the bottom box put 3
SCALE FACTOR 1:3
Answer:
opposite sides are congruent for first under given
AD=AD for reflective property of congruency
next one under given is definition of perpendicular lines
and last box is acd=bdc
